I've been graciously receiving CiscoPress books for review for a while now so it's about time I actually, you know, review one. First up is the newest CVoice book:
I'm going through a re-cert process right now but I'm also trying to head towards the CCVP. CVoice is one of my required tests for both of these so it's the first one I'm tackling. Earlier this year Cisco changed the requirements for the CCVP and rolled the old Gateway/Gatekeeper (GW/GK) test into CVoice and called it version 6. Luckily this book was written just for that!
I took the test blind once to see what was on it. Failed miserably. I then began reading the book. I found the book to be very comprehensive in the early sections. Specific questions that I know I got wrong I was able to track down the general answers to. This book isn't some kind of cheat sheet but it does seem to follow the test pretty well.
I felt the sections on protocol characteristics, h.323 Gateways and MGCP configuration were all pretty thorough, as it relates to the test. The section on Dial Plans was especially good.
The one section I found to be short was CUBE. The CUBE section explained the general nature of the configuration sufficiently but I thought it stopped short of a really detailed description. I would have liked more detail in this one section.
Of the "Official" test guides I've read in the past I thought this was one of the better ones. A thorough reading of it will prepare you for the test, as well as deepening your understanding of voice gateways in the Cisco world.
